The flow control type can be divided largely into 13 control types.
Control 1:
Determines the priority using the output priority.
Control 2:
Determines the priority using the output priority and performs surveillance on
the contract band. If the detected flow breaches the contract band, abolishment
processing is performed.
Control 3:
Determines the priority using the output priority and performs surveillance on
the contract band. If the detected flow breaches the contract band, the priority is
lowered.
Control 4:
Rewrites DSCP and uses it to determine the priority.
